“…Following the first successful application of RFN in trigeminal neuralgia (17), it was then applied to the sacroiliac joint causing chronic back pain and the facet joints (18,19). It then started to be applied to cases of cervical facet and discogenic pain (20,21) and has also been used in cancer pain treatment (7).…”

“…As these treatments are sometimes unsuccessful, surgical interventions such as arthroscopy or total knee replacement are required. However, surgical interventions may not be possible because of comorbidities in the patient (7). Therefore, radiofrequency neurotomy (RFN) applied to the genicular nerve may be an alternative treatment method that can be applied successfully with few complications.…”

Background/aim: We investigated the short-and medium-term effectiveness of genicular nerve radiofrequency (RF) applied in patients with chronic knee pain due to osteoarthritis. Materials and methods:Radiofrequency was performed in 49 patients with a diagnosis of knee osteoarthritis. VAS and WOMAC were measured at baseline and at 1, 4, and 12 weeks postprocedure. Under fluoroscopic guidance, the cannula was advanced percutaneously towards the area connecting the shaft to the epicondyle. The RF electrode was inserted through the cannula and the electrode tip temperature was raised to 80 °C for 90 s. One RF lesion was made for each genicular nerve.

“…[22] Benzer olarak bir başka olgu serisinde de RF uygulaması sonrası WOMAC skorundaki düzelmenin anlamlı olarak bir yıl kadar sürdüğü vurgulanmıştır. [23] Ancak bu iki bildirinin hasta sayı-larının oldukça az olması ve kontrol grubunun olmaması nedeniyle RF uygulamasının dizin fonksiyonel düzelmesinde uzun dönem etkili olduğunu söylemek oldukça güçtür.…”

ÖZAmaç: Bu çalışmada geniküler sinirlere radyofrekans termokoagülasyon (GSRFT) uygulamasının diz osteoartriti (OA) ağrısı ve fonksiyon kaybı üzerindeki etkinliği araştırıldı. Hastalar ve yöntemler:Şubat 2015 ve Mayıs 2015 tarihleri arasında, en az üç aydır devam eden ve konservatif tedaviye yanıt vermeyen diz OA ağrısı olan 40 hasta (8 erkek, 32 kadın; ort. yaş 63.9±9.2 yıl; dağılım 50-80 yıl) çalışmaya dahil edildi. Bütün hastalara floroskopi altında GSRFT uygulandı. Hastalara işlem öncesi, işlem sonrası birinci ay ve üçüncü ay görsel analog ölçeği (GAÖ) ağrı skorları ve Western Ontario McMasters Osteoartrit İndeksi (WOMAC) uygulandı. Birinci ay ve üçüncü aydaki ağrı ve fonksiyon durumları işlem öncesindeki duruma göre değerlendirildi. Bulgular:Hastalarda GSRFT uygulaması sonrası birinci ay ve üçüncü ay GAÖ ağrı ve değerlerinde anlamlı düşüş görüldü (p<0.001). Bununla birlikte üçüncü ayda hastaların yarısından fazlasında GAÖ değerleri 4 ve üzerindeydi. WOMAC ağrı, tutukluk, fonksiyon alt gruplarında ve WOMAC toplam skorunda birinci ay ve üçüncü aylardaki azalma anlamlıydı (p<0.001). Hastaların hiçbirinde yan etkiye rastlanmadı.Sonuç: Çalışmamızın sonucunda GSRFT uygulamasının kronik diz OA ağrısı ve fonksiyon kaybında etkili, minimal invaziv bir yöntem olduğu düşünülmektedir. Ancak bu bulgular kontrollü, randomize ve daha büyük gruplar üzerinde daha uzun süreli yapılan çalışmalarla desteklenmelidir.Anahtar sözcükler: Geniküler sinir; diz; osteoartrit; radyofrekans termokoagülasyon. ABSTRACTObjectives: This study aims to investigate the efficiency of radiofrequency thermocoagulation on genicular nerve (RFTGN) application on knee osteoarthritis (OA) pain and loss of function. Patients and methods:Between February 2015 and May 2015, a total of 40 patients (8 males, 32 females; mean age 63.9±9.2 years; range 50 to 80 years) with knee OA pain, that has continued for at least three months and has not responded to conservative treatments, were included in the study. All patients were performed RFTGN under fluoroscopy. Visual analog scale (VAS) pain scores and the Western Ontario McMasters Osteoarthritis Index (WOMAC) were applied to patients before the procedure, one month and three months after the procedure. Pain and functional status in the first month and third month were assessed according to the situation before the procedure.Results: A significant decrease was observed in the patients' VAS scores in the first and third month after the RFTGN application (p<0.001). In addition to this, more than half of the patients had VAS scores of 4 and above in the third month. Decrease in WOMAC pain, stiffness and function subgroup scores, and WOMAC total score in the first and third month was significant (p<0.001). No side effects were seen in any of the patients. Conclusion:As a result of our study, we conclude that RFTGN application is an effective, minimally invasive method for the treatment of chronic knee OA pain and loss of function. However, these findings should be supported by longer-term studies conducted in contr...

“…It is an interventional pain therapy that seems less popular than newer techniques such as pulsed radiofrequency ablation [11]. Brechner et al [12] studied the effects of percutaneous cryoneuroablation of the lumbar facet in patients with neck and lower back pain, finding that there was 70% pain relief after 1 hour, a relief which lasted 1 week and which by 3 months had returned to the baseline.…”

Background: Cryoanalgesia, also known as cryoneuroablation or cryoneurolysis, is a specialized technique for providing long-term pain relief. Methods:We present here retrospective data on pain relief and changes in function after cryoanalgesia techniques: we describe the effect of this procedure on articular facet syndromes, sacroiliac pain and knee pain. Results: We reviewed the records of 18 patients with articular lumbar facet pain, knee pain and sacroiliac pain. The Visual Analog Scale and Patient's Global Impression of Change scale show satisfaction at 1 month after cryoablation, with the best scores after three months. Only three patients showed a worse condition than the first month. Conclusion: The majority of patients experienced a clinically relevant degree of pain relief and improved function following percutaneous cryoanalgesia.
